sired, and also ermitting detachment or disconnection of s iaking mechanism to allow removal of table in direction away from such mechanism for applying new wire.

The connections between the two middle members 43 and table are shown in Figs. 2 and 7. They comprise straps 51 connected to yokes 52 which are on opposite sides of uprights 43, yoke members 52 sliding between rolls 53-53 on boxes 54 which enclose uprights 43 and are also connected with straps 51. Boxes 54 are provided with openable sides 55 normally held in position so as to My-invention relates to Fourdrinier paper making machines, and particularly to shaking mechanism therefor.

One of the objects of the invention is to provide a simple, practicaland advantageous construction of Fourdrinier machine capable of being shaken and of shaking mechanism therefor.

Another object of the invention is to avoid 1o vibration as a result of the operation of the shaking mechanism- 1 Another object of the invention is to provide a shaking mechanism which shall be especially adapted to cooperate with a Fourdrinier machine having a table made laterally removable to permit application of a new wire and also having a table vertically adjustable at its feed end to control character of fiber.

Other objects of the invention will appear and be pointed out hereinafter.

In the accompanying drawings Fig. 1 is a plan of the table of a Fourdrinier machine and shaking mechanism therefor, embodying my present invention;

Figs. 2 and 3 are cross-sections taken on line 22 and 33, respectively, in Fig. 1 on an enlarged scale; I

Fig. 4 is a plan view of the mechanism shown in Fig. 3;

Fig. 5 is an end elevation of the feed .end portion of the table;

Fig. 6 is a View taken on line 6-6 in Fig. 3;

Fig. 7 is a section. on line 77 in Fig. 2; v

Fig. 8 is a view of a detail of construction;

Fig. 9 is a section on line 99 in Fig. 1 and Fig. 10 is a section on line 10-10 in Fig. 9.

Referring to the drawings, I show the table section 1 of a Fourdrinier machine .having rolls ?-2 and a shaking-mechanism at the rear thereof, as shown in Fig. 1.

This shaking mechanism comprises a series (four are shown in Fig. 1) of upwardly extending reciprocatory or vibratory members 43-43 mounted on rock shaft 44, which is supported by bearings 4545 located on the vfioor,--whereby shaft 44 is low and vibration is prevented. Upright members 43-are connected with table section 1 by detachable connections permitting table to be shaken as de- By unscrewing the latter, side may be swung about pivot bolt 58 so as to open box 54 and allow separation of same from'upright 43. The connection for the right hand end member 43 is shown in Figs. 9 and 10. It comprises a strap 51, such as previously described, but same has a pivotal connection 59 with the jointed section 1 of the table, and also a connection 60 with the shaking section 1 of the table, whereby both sections are shaken. The connection for the left hand- It comprises a box 61, open at one side and having an inclined side and a connection 63 for the brest roll bearing 64. Section 1 of table is mounted on flexible members 41 whose lower ends are secured to channel members 42, to permit shaking of rolls 2 and wire thfii'eon without shaking the remainder of the -ta e.

Vibratory members 43 are actuated by rocking of shaft 44 by vertically vibrating arms 47 actuated by reciprocating members 47 a controlled by shaft 47 which is turned by gear connection with power shaft 48, so that rotation of latter will vibrate members 43 and so shake table.

Thus the whole table section 1 and brest roll also may be shaken as desired and also detached from shaking mechanism to permit removal of table for applying new wire, as shown in Figs. 2 and 3.

Certain subject matter of this application is disclosed and claimed broadly in my copending applications, Serial No. 595,258, filed October 18, 1922; Nos. 648,959, 648,960,
